Polyureaurethane composition having improved color stability |
| abstract |
The present invention provides a polyureaurethane composition comprising: a) the reaction product of: 1) a polyurethane prepolymer comprising a polyisocyanate and at least one OH-containing material; and 2) an amine-containing curing agent, wherein the equivalent ratio of the amine-containing curing agent of 2) to the polyurethane prepolymer of 1) is from 0.75 to 0.98; b) a hydroxyphenylbenzotriazole present in the polyureaurethane composition in an amount from 0.75 to 1.1 percent, based on the total weight of resin solids in the polyureaurethane composition; and c) a multifunctional hindered phenol type anti-oxidant present in an amount from 0.25 to 1.5 percent, based on the total weight of resin solids in the polyureaurethane composition wherein b) and c) are combined in amounts to provide the polyureaurethane composition with a Δ Yellowness Index of less than 1.85 in the 60/80 Accelerated Warehouse Aging Test. |
